Judge Michael White is to begin his summing up in the Brian Murphy manslaughter trial today.
Mr Murphy died outside Club Anabel in Dublin on August 31st, 2000, after being kicked and punched.
Mr Sean Mackey (23), from South Park, Foxrock; Mr Desmond Ryan (23), from Cunningham Road, Dalkey, all Co Dublin, and Mr Dermot Laide (22), from Rossvale, Castleblayney, Co Monaghan, have pleaded not guilty to the manslaughter of Mr Murphy (18) at Sussex Road.
Mr Andrew Frame (22), from Nutley Lane, Donnybrook, had also denied that charge but on Monday Judge Michael White directed that he be found not guilty because of insufficient evidence against him.
The four former Blackrock College students have also denied committing violent disorder by using or threatening to use unlawful violence on the same date.
Over the last two days the court has heard prosecution and defence barristers deliver their closing speeches.
The jury of eight men and four women is expected to retire to consider its verdict on Monday.
